市盈率(P/E)是市场价格除以企业EPS (每股收益)的比率。P/E已经给了，但是需要确定使用其他信息来判断市场价格。EPS是$7，乘以P/E 8，因而股票价格是$56。每股收益$7是给普通股股东的收益$14,000,000除以发行在外的普通股2,000,000。普通股股东的收益(E to CS)计算如下
EBIT = 息税前收益。E to CS = [(EBIT – 利息)(1 – 税率)] – (优先股股利)
E to CS = [($35,000,000 – $5,000,000)(1 - 0.4)] – ($4,000,000)= [$30,000,000(0.6)] – ($4,000,000) = $18,000,000 – $4,000,000 = $14,000,000
